There was only the mock-up of
Aichi C4A1
13 Shi experimental fast reconnaissance aircraft
built by Aichi under factory designation
AM-20.
Development of the project was relinquished as the Kaigun Koku Hombu decided to order
the
Mitsubishi C5M airplanes instead.
Aichi C4A1 was one-engined, two-seat ( pilot + gunner ) low-wing monoplane
with retractable undercarriage, all-metal construction with fabric covered ailerons and rudders.
The aircraft has to be powered by 14-cylinder Mitsubishi MK2A Zuisei 12 ( Ha-31-12 ) air-cooled radial engine
of 643 kW start power and 574 kW at 3600 m. Changeable pitch two-bladed propeller.
No datas about dimensions. Armament : one
Type 92 7,7 mm machine gun.
There was only the initial project of
Aichi B8A1 Mokusei
20 Shi experimental special torpedo - bomber aircraft
made to specification No 20 Shi calling for development of the
Aichi B7A2 Ryusei.
The plane had to be faster, more nimble and manoeuvreable
and had to have smaller dimensions. Project was designated
AM-26 by the Aichi factory
and was stopped 'cause of Japan capitulation.
The aircraft has to be powered by 18-cylinder Mitsubishi MK9A-Ru ( Ha-43-12 ) air-cooled radial engine
of 1618 kW start power, 1567 kW at 1800 m. and 1265 kW at 9500 m. Changeable pitch four-bladed propeller.
No datas about dimensions. Armament : two
Type 5 30 mm cannons in wings
and one
Type 2 13 mm gunner's machine gun + various combinations up to 800 kg of bombs
or 800 kg torpedo.
Unfortunately I have no photos or drafts and I'm myself looking for them
